Answer:
Carbon (C)
Explanation:
Carbon is the only nonmetal there and covalent bonds happen between two nonmetal atoms
Four binary ionic compounds that could be formed from each of these ions are;
- Zn^2+ - ZnCl2, ZnI2, ZnBr2, ZnF2
- Pb^4+ - PbF4, PbCl4, PbBr4, PbI4
- Br^- - MgBr2, NaBr, CaBr2, KBr
- S^2- - CaS, MgS, Na2S, K2S
<h3>What are binary ionic compounds?</h3>
Binary ionic compounds are those compounds that contain only two elements. The ionic compounds are those compounds that contain ions. The compounds are able to dissolve in water and they have high melting and boiling points.
Now, four binary ionic compounds that could be formed from each of these ions are;

Answer:
77.98 g/mol ≅ 78.0 g/mol.
Explanation:
- The molar mass of any compound can be calculated by the sum of the atomic masses of different atoms in the compound multiplied by its no. in the compound.
Molar mass of Al(OH)₃ = (Atomic mass of Al) + 3(Atomic mass of O) + 3(Atomic mass of H)
Atomic mass of Al = 26.98 g/mol. & Atomic mass of O = 16.0 g/mol & Atomic mass of H = 1.0 g/mol.
<em>∴ Molar mass of Al(OH)₃</em> = (26.98 g/mol) + 3(16.0 g/mol) + 3(1.0 g/mol) = <em>77.98 g/mol ≅ 78.0 g/mol.</em>
